I Are Peak Moment and Peak Torque Equivalents in Biodex Dynamometry Measurements?

AI Thread Summary
Peak moment and peak torque in biodex dynamometry measurements refer to similar concepts but are used in different contexts. While engineers may refer to peak moment, physicists typically use the term peak torque, as torque specifically involves rotational force. Both terms can be expressed in Newton-meters (Nm), but they may not always represent the same physical quantity depending on the context of the measurement. Understanding the distinction is crucial for accurate interpretation of knee muscle strength outcomes. Clarifying terminology can help avoid confusion in reporting and analyzing dynamometry results.

TL;DR Summary
Peak Moment vs. Peak Torque in Knee Extension
Apologies if this is in the wrong section as it isn't particularly medical in nature despite it being about the body.

I am currently conducting a rapid review with outcomes of knee muscle strength. This is measured by biodex dynamometry, which assesses numerous values including Peak moment (Nm). My issue is that another study has also used the same equipment but reported values of (Nm) as peak torque which makes sense as the movement in question is rotational (Think bent knee -> straight knee, the peak force produced by this movement). My question is whether these two values are the same but have been reported differently or if it is a completely different value with the same unit of measurement.

Thanks!

Welcome to PF.
What an engineer calls a moment, a physicist calls a torque.
The least confusing term would probably be torque.

In physics, a moment is an expression involving the product of a distance and physical quantity
So a moment can involve any physical quantity.
https://en.wikipedia.org/wiki/Torque said:
In physics and mechanics, torque is the rotational equivalent of linear force.
A torque is a moment that specifically involves a force.

And there is also a couple, which is a special case of a torque:
https://en.wikipedia.org/wiki/Couple_(mechanics) said:
In mechanics, a couple is a system of forces with a resultant (a.k.a.net or sum) moment but no resultant force.
So in the following figure, the top arrangement is a force producing a torque. But the bottom arrangement is a resultant force F (not producing a torque), and two forces C producing a couple. They both have the same effect on the system.

Have both values the same magnitude in Newtons-meter?
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Hello! Let's say I have a cavity resonant at 10 GHz with a Q factor of 1000. Given the Lorentzian shape of the cavity, I can also drive the cavity at, say 100 MHz. Of course the response will be very very weak, but non-zero given that the Loretzian shape never really reaches zero. I am trying to understand how are the magnetic and electric field distributions of the field at 100 MHz relative to the ones at 10 GHz? In particular, if inside the cavity I have some structure, such as 2 plates...
